This quest requires you deliver 12 power cells during the escape from Vader matches. The first playthrough I got credit for the 4 in the tutorial and I managed to get 3 more before I ran out of respawns. So it counted 7/12 on the quest.
I tried another playthrough and this time I did the 4 power cells in the tutorial part and it gave me credit for 2 of them putting me at 9/12. But it did not count the other two. I thought, okay maybe because it is the tutorial. So I went ahead and played through the match and this time I got all 4 of the other powercells, then I manage to get the item on the ship we are looking for and I managed to escape to win the match. But it did not credit me beyond the first two tutorial power cells and seems to be stuck at 9/12.
I even played a THIRD match and this time it did not count the tutorial at all. So I grabbed two of the power cells during the match and it did not count those either. To be clear, when it froze at 9/12, I gathered 12 more power cells as I described above and it did not count any of those.
That is completely unacceptable. I want to complete the quest for the star wars rewards those quests help you achieve. Escape from Vader is not a fun mode and I am ONLY playing it to try and complete this quests. But your bug is preventing me from getting credit for that quest and if I miss out on rewards because of bugs in your game, it is a complete let down.
